| Question | Answer |
|---|---|
| Skeletal system | support the body, protects vital organs, storage of minerals, and movement |
| Nervous system | detect stimuli, transmit information, to generate a reaction |
| Cardiovascular system | to take in oxygen, passing it to cells, collect CO2 and remove it from the body |
| Excretory system | collect liquid waste and remove it from it from the body |
| Endocrine system | create and transport hormones |
| Reproductive system | create and allow for the passage of gametes and to provide a protective environment for a developing fetus |
| Digestive system | break down food, absorbs nutrients, and prepare solid waste for removal from the body |
| Tendons | connect muscle to bone |
| Ligaments | connect bone to bone |
| Arteries and veins | contains blood so the oxygen-rich and the oxygen-poor blood doesn't mix |
| Kidney | filters waste from the body |
| Urethra | tube that allows urine collected in the kidney to flow to the urinary bladder |
| Ovary | produces estrogen and progesterone |
| Fallopian tubes | transports ovum |
| Pituitary Gland | produces growth hormones and other control hormones |
| Penis | transports sperm |
| Gall bladder | stores bile |
| Small intestine | absorbs nutrients from newly digested food |
| Rectum | condense and transport waste to the anus |
| Neuron | nerve cell |
| What are two things that make up nervous tissue? | Neurons and their supporting cells |
| Myelin sheathing | allows the impulse to travel along the axon more efficiently |
| Electrical signals | Action Proteins |
| Nerve impulses in humans | They create movement, perception, thought and emotions |
| Dendrites | extend from the cell body like antennae |
| Cell Body | contains the nucleus and most of the organelles |
| Axon | transmits an impulse away from the cell body |
| Axon terminals | responsible for releasing neurotransmitters |
| Cell in the myelin sheathing nervous system | Schwann cells |
| Gap in the myelin sheathing | Nodes of Ranvier |

| Gap in the myelin sheathing | Nodes of Ranvier |
| Inside the cell membrane | Negative |
| Outside of cell membrane | Positive |
| Membrane protein | inner surface has a different electrical charge than the outside surface of the cell. |
| Direction of an ion | Concentration of the ions, ability to ions to move across the membrane |
| Membrane potential unit measures | Voltage |
| Ions | allows charged particles to pass through the cell membrane |
| Resting membrane | a neuron is not transmitting an impulse |
| Action protein | moves down the axon like a wave |
| Electrical charge | inside of the cell membrane becomes more positive than the outside |
| Resting potential in units | -70mV |
| Active transport mechanism | Sodium-potassium pump |
| Synapse | Gap between nerve cells |
| Two nerve cells | Neuron don't directly touch each other |
| Chemicals released by axon terminals | Neurontransmitters |
| Acetylcholine | used in muscles |
| Glutamate | used in brain |
| Norepinephrine and Dopamine | feelings of pleasure |
| Enkaphalines and Endorphins | block pain signals |
| Excitatory Reaction | Causes a new impulse to be sent |
| Inhibitory Reaction | causes no new impulse to be sent |
| Central nervous system | brain and spinal cord |
| Peripheral nervous system | sensory division and motor division |
| neurons on the brain? | 100 billion neurons |
| Cerebrum | largest, learning, memory, perpection, intellectual, divided by hemispheres by a central groove |
| Corpus callosum | connects 2 hemispheres |
| Cerebral cortex | the outer most layer of the cerebrum. gray matter mostly cell bodies location of motor and sensory |
| Cerebellum | found at the base of the brain, balance, posture, movement. coordinates the spinal cord and cerebrum. Contracts the muscle to make movement |
| Brain Stem | Important for memory, learning, and emotions. thalamus and hypothalamus linked to the cerebral cortex by the limbic system |
| Spinal cord | links to the brain to the peripheral nervous system controls the sudden of muscles called reflexes |
| Dorsal root | sensory neurons that carry information to CNS |
| Ventral root | motor neurons that carry information from CNS to muscle and glands |
| Relexes | Somatic Nervous system |
